The length of a rectangle is 4 times the width. The area is 676 square meters. Find the length and width of the rectangle.

width=13cm and length=52cm

Step-by-step explanation:

let x represent width=x

since the length is 4 times the width, length=4x

Area=length × width

676=4x × x

676=4x²

To find x divide both side by the co-efficient of x which is 4

676/4=4x²/4

169=x²

Then find the square root of both sides to get x

√169=√x²

13=x

Therefore x=13

Now we can find the length and width since we replaced length by 4x and breadth by x

therefore we need to substitute x by 13

length=4(x)

=4(13)

=4 × 13

=52cm

Breadth=x

=13cm

Part A: Total cost = 10 + 4s

Part B: Solving for s = 2

10 + 4 * 2 = US$ 18

Correct statement and question:

Write an expression to represent admission to a zoo of $10.00 and the cost of special exhibits s at $4 each. Evaluate your expression when s = 2.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Admission to the zoo = US$ 10

Special exhibit cost (s) = US$ 4

2. Evaluate your expression when s = 2

Total cost = Cost of admission + (s) * Special exhibit cost

Total cost = 10 + (s) * 4

Total cost = 10 + 4s

3. Solving for s = 2

10 + 4s

10 + 4 * 2 = US$ 18
